The disquieted elements agitate your blood and your mind. the steady air suffocates you to death. you start to feel nothing goes right in life, you start to hate everything/everyone of your surroundings, you start to consider some changes.

What makes you become a traveller roaming around in this world?
are you looking for something which you can't find from where you are?
or are you looking for something that you're not sure what it is and where it is?
or you don't even know if you're looking for something and what you're looking for?
or you're escaping from something?

So everytime when the departure day's approaching, the melody will pop up in mind spontaniously:
So kiss me and smile for me
tell me that you'll wait for me
hold me like you'll never let me go
cause i'm leaving on a jet plane
dont know when i'll be back again
